Symfony version(s) affected

6.2.3

Description

The performance of the v6 DomCrawler component is somewhere in the region of 10x slower than that of v5, to do exactly the same work. I process in order of hundreds of thousands of pages per day so a 1000% slow-down is very obvious and also completely impractical (what should take 1 hour now takes 10). If I discovered DomCrawler today I would simply dismiss it as unfit for purpose, but since I've been using it for many years, I am aware simply downgrading to v5 will "fix" the issue.

How to reproduce

Compare v5 to v6 performance for high volume page parsing. In case you want to use exactly the same parser I do, see: https://github.com/Provider/Steam/blob/master/src/Scrape/AppDetailsParser.php
